The 1st-grade highway is the highest grade highway in the common highway in our country, and it is the very important part of highway network in our country. For us posting our most intention to the road itself rather than the environment along the road in the road design process. So it causes that after the completion of the 1st-grade highway, it will undertake the impact of land development beside the road two or three years later, and operating efficiency decreases and traffic safety will not secure. Meanwhile, there is not detailed design standard of exit and entrance of 1st-grade Highway in the Design Code of Highway Route, and the management of access to 1st-grade highway is weak. So traffic accidents often happen in the exit and entrance of 1st-grade highway and the traffic accident rate of 1stgrade highway in our country is the highest. At first the paper analyzes traffic character of 1st-grade highway, then traffic characters of exit and entrance, influential factors of exit and entrance and traffic safety problems in the exit and entrance are analyzed. At last, the paper studies on the application of access management in the traffic safety of exit and entrance in 1st-grade highway from the aspect of policy management and operation design.
